Integrating Flash in DDR4 DIMMs

Micron came up with a new product that adds flash memory on " the DDR4 bus in 18 months... leapfrogging today's solid state drives on PCI Express to open up new applications. ... The move gives flash a new position in the computer memory hierarchy, ahead of todayĆ¢€™s solid state drives that ride the PCI Express bus.
The Hybrid DIMMs will be more expensive than SSDs but likely offer greater performance with memory access times measured in nano- rather than microseconds."

This is an interesting product that leverages the speed of flash and places it higher in a computer system hierarchy. Intel has been working on developing other products that add flash memory closer to the microprocessor (see April 5, 2012 Flash is not just about storage )
